Crystal structure of Bone Morphogenetic Protein-7 (BMP-7) in complex with the secreted antagonist Noggin

The structure was published by Groppe, J., Greenwald, J., Wiater, E., et al., Vale, W.W., Izpisua-Belmonte, J.C., and Choe, S., in 2002 in a paper entitled "Structural Basis of BMP Signalling Inhibition by the Cystine Knot Protein Noggin" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.42 Å and deposited in 2002.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely Bone Morphogenetic Protein-7 and Noggin.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotetramers.
